The thing is, I only see one copy of FileMaker Server 13 running. I don't know how to make the other copies stop.
The problem is happening on a MacMini Server running 10.10.3 without Server 4 running. Just FileMaker Server, though even that isn't working now. The only solution I've come up with so far is uninstalling FM Server and reinstalling it again. Can't figure out what the root cause is.
Anyone have any ideas?
